I have a spreadsheet with formulas in certain cells - for example in B2 I have =IF(A2="","",(B1)) but if I enter a date in A2 nothing appears in B2 unless I select B2 and click the fx button and okay the box that appears. I did read to check that I hadn't selected Text for these cells but I haven't. So I'm not too sure what I'm doing wrong and any suggestions would be gratefully received.
